The invention belongs to the field of
network data exchange equipment, and particularly relates to a mimic switch, a network device and a
system, and the mimic switch comprises a switch
chip which isused as a data forwarding entity to complete regular forwarding of opposite-end data; a mimic scheduler which is responsible for uploading the message data to the heterogeneous control engine executorand issuing the message data to mimic scheduling of the exchange
chip; and a plurality of heterogeneous control engine executors which are used for receiving messages sent by the mimic scheduler andcarrying out
data processing and feedback through the heterogeneous
equivalent function executors. According to the invention, a heterogeneous control engine and a scheduler are introduced into the
control layer to realize dynamic heterogeneous redundancy of the
control layer; aiming at unknown vulnerabilities, Trojans, rear
doors and the like, seamless switching of a dynamic
system is ensured, and the method has the advantages of redundancy, heterogeneity, dynamics,
negative feedback characteristics, service jolting removal characteristics, safety mode division, endogenous safety characteristics, defense compatibility and the like, and has important guiding significance for development of network switching equipment.
